In the pre-retcon timeline when we were just meeting god tier Aradia with blind Sollux on Vriska's ghost ship, Vriska said that Aradia's powers would become useful once they found the "treasure". Sorry if my memory is bad but what exactly was that treasure and what would Aradia have had to do with it?

The treasure is Caliborn’s juju, the white intangible house. Aradia has telekinesis so Vriska brought her along so she could move the juju.

When Aradia talked about having a corpse party, she did not mean dancing around with dead bodies all over the floor like most of the fandom believes, but rather meant having a proper funeral that was multicultural for both her troll and human friends.

What was the purpose of the Scratch?

The Scratch is meant to reset the session and it’s conditions to make a more favorable session. 

Do you know who drew Aradia's god tier talksprite?
